Optimizing the selection of actuators for reconnaissance flying robot
Vítek, Milan ; Gábrlík, Petr (referee) ; Kříž, Vlastimil (advisor)
Purpose of this semestral thesis is to create a set of recommendations for choosing optimal motors, propellers and batteries for multi rotor flying vehicles with respect to flight time and flight dynamics. In this thesis you can find analysis of motor, propeller and battery properties and characteristics and their dependencies. Based on these findings there is a set of rules to choose optimal components and set optimal working point. This thesis also describes the design and implementation of a device used to measure the main characteristics of motors and propellers.

Calculation and measurement of induction motor parameters
Nekovář, Martin ; Hájek, Vítězslav (referee) ; Vítek, Ondřej (advisor)
The theme of this master´s thesis is calculation and measurement of the parameters of induction motor. The thesis is divided into several parts. The first and the second part describes the general construction and operating principle of asynchronous motors. The construction includes a description of each part of induction motor, which consists of stator and rotor. The thesis deals with three-phase symmetrical and asymmetric single-phase motors. Principle of operation with using the rotating magnetic field, which is circular at three-phase motors, single phase motors have field elliptical shape. The next part contains the motor replacement scheme. The fourth part contains the calculation of motor´s parameters through the formulas. In this part the procedures for obtaining parameters of the replacement scheme of induction motor are defined. The process of calculating the parameters of the motor replacement scheme of threephase asynchronous motor is created according to given documentation is the next part for the certain type. The next content of the thesis describe finite element method, simulation and measurement of asynchronous motors to get of parameters from no-load and short-circuit test. The comparison of the results from measurement, analytical calculation and from simulation is given in the last chapter.
